BUSHING-VALVE AND FAOCET-COUPLING,

SPECIFICATION forming part of Letters Patent N 0. 725,912, dated April21, 1903. Application filed February 11,1902. Serial No. 93498. (Nomodel.

To all whom it may concern: 9

Be it known that I, BENJAMIN C. ANDERSON, a citizen of the UnitedStates, residing in the borough of Brooklyn, in the city and State ofNew York, have invented a certain new and useful Improvement inBushing-Valves and Faucet-Couplings, of which the following is aspecification.

My invention is intended more especially for fitting in the thick woodenends of beerbarrels and will be described as thus applied.

There have been many efforts to provide a sufficiently liberal circularaperture in the Wood and to insert therein a metal bushing, which shallbe permanently set and endure all the wear which subsequently accrues inmany insertions and removals of the interior parts. My bushing thusapplies. It is important that the application and removalof the parts beeffected with ease and rapidity. It is important to give a largefiltering area, and at the same time to have but a small valve. Myinvention attains this and also a central delivery, avoiding thenecessity for filtering laterally into the coupling.

I have devised important improvements in the details of construction andin the mode of operation, which are set forth in the accompanyingdescription and pointed out in the claims.

The following is a description of what I consider the best means ofcarrying out the invention.

The accompanying drawings form a part of this specification.

Figure 1 is a central longitudinal section, showing the bushing with thecoupling attached. Fig. 2 is a corresponding section, partly inelevation, with the coupling, removed. Fig. 3 is an elevation showing aportion of such coupling. Fig. 4 is a perspective view of thelongitudinal plug inclosed in the bushing. Fig. 5 is a transversesection on the line 5 5 in Fig. 1. Fig. 6 is a corresponding sectionshowing the same with the plug turned into the closed position. Fig. 7is a section on the line 7 7 seen from the right in Fig. 2. Fig. 8 is aperspective view of a pin removed. Fig. 9 is a partial transversesection on the line 9 9 in Fig 2.

Similar letters of reference indicate corresponding parts in all thefigures where they appear.

A is the wood of the barrel, and B a hollow casting of brass engagedtherein by screwthreads, as indicated, and which I will term thebushing. It extends into the interior of the barrel. The inner end B hasliberal perforations b. The extreme inner end is internallyscrew-threaded and receives a perforated disk O c, screw-threaded on itsexterior and having a circular hole 0 in the center, which latterreceives a pin D, extending toward the center of the barrel in the axialline of thebushing. This pin has longitudinal channels or deep flutes d,the purpose of which Will presently appear.

I provide a rotatable plug E, extending in the axial line of theinterior and capable of being partially rotated by a moderate force. Theexterior of this plug isfinished conically. A portion B of the interiorof the bushing B is finished with a corresponding taper, with theaddition of longitudinal channels 1) b which extend only a portion ofthe length of the tapered part B The pin D extends into a correspondingcircular holee in the inner end of the axis of the tapering plug. Theouter end of the pin D is contracted bya shoulder dand, matches in thehole c in the disk. When the disk is screwed up, it presses the pin, andconsequently the plug E, endwise into a closer fit by its action on theshoulder d. It is capable of yielding slightly, so thatin case there isany imperfection'inthe manufacture the plug may be governed entirely byits bearing in the tapered interior B ;of the bushing. The latterbearing may beadj usted with great delicacy by the action of thescrew-threads induced by the partial turning of the disk O in onedirection or the other.

A sufficient length near thev outer end of the plug E is triangularwhere it extends into the larger space beyond the close-fitting taperedportion of the bushing. Such triangular portion of the plug may beconsiderably smaller than shown; but I prefer to make it of about aslarge size as the construction will allow. The extreme outer end istapered rapidly, constituting a pyramidal end E. An axial passage eextends a considerable por- ICO tion of the length of this plug. From itbranches e lead diagonally outward through the pyramidal end E. end ofthe passage 6, communicates with a transverse passage 6 which may be soliberal as to allow a sufficient flow when the plug is turned so thatthe ends of this hole coincide with the channels b b So far as yetdescribed it will be understood that when the plug E has its nicelyfinished conical surface held to a fair but gentle bearing against thecorresponding tapered surface B of the interior of the bushing it willwhen standing in one position allow the beer to flow along the channelsI) b inward in both directions through the hole 6 thence along the axialpassage 6, and finally outward through the apertures e When, on thecontrary, the plug is turned a quarterrevolution, as shown in Fig. (5,bringing the hole 6 out of coincidence with the channels Z)" 6 theescape is tightly stopped. There being two of the channels 19' 19 givesadmission for liquor into each end of the transverse passage 6 thusincreasing the How and balances the pressure on the opposite side of theplug.

When, as usual, the bushing B is of only moderate thickness, the largediameter of the bore in the outer end of the portion B limits the depthwhich is allowable for the channels 1) 12 I provide additional passagesby means of an additional transverse hole (2 parallel to the hole e Whenthe plug is turned in the open position, the liquid can not only fiowdirectly from the chamber 11 into the channels 1) b through thecontracted outer ends of the latter, but also can flow along the flutesd in the pin D and outward through the hole 6 to reinforce the streamsflowing through those channels, thus promoting the freedom of discharge.

The interior of the outer end of the bushing is formed withlongitudinalgrooves, serving as coupling-passages, which extend from theouter end longitudinally inward a little distance, as indicated by b b,and thence are continued circumferentially and slightly heli cally onthe interior a quarter-revolution, as indicated by b If.

G is a coupling-piece, of brass or other suitable material, inserted andremoved at will. It has a sufficient axial passage g, through which whenin position the heer may flow when the plug E is turned to permit it.The inner end of the passage g is enlarged and made of triangularcross-section, as indicated by g, fitting closely but easily on thetrian gular portion E of the plug. On the coupling-piece are projectionsG G The projection G is wider than the projection G and the longitudinalaperture 6 is correspondingly wider than the groove Z). (See Fig. 9.)The periphery of the end of the coupling-pin G is provided with apacking-ring of soft rubber G This should be so wide that it bearsfirmly on the bottom of the recess and prevents any lateral flow of thebeer. The same The other, the inner.

partial rotation of the coupling-piece G which through the projectionsG,G and the grooves 19 b b 12 engages it tightly with the barrel actsthrough the engagement of the triangular inner end of its aperture g onthe triangular portion E of the plug to effect the turning of the plug.Thus the same motion which insures the firm and tight engagement of thehose turns the plug to allow the beer to flow, and the shutting off ofthe beer is insured by the same movement in the reverse direction whichdetaches the coupling.

My invention provides a filtering-surface covering the whole rear diskand a portion of the bushing adjacent thereto. The chamber in the innerend. of the bushing receives the strained liquid and flows it throughliberal channels, which coincide when the plug is turned into the openposition, but are tightly restrained when the plug is in the closedposition. The liquid is delivered through the center of the plug. Thesequalities have been before separately involved in apparatus of thiskind, but my combination is unusually efficient.

Modifications may be made without departing from the principle orsacrificing the advantages of the invention. The pyramidal end E of theplug may be omitted, but I prefer to retain it, as it asists to guidethe parts in applying the coupling-piece. It will be understood that theouter end of the coupling-piece may be fitted with a faucet-plug andadapted for delivery of the beer by single glasses or may he variouslyotherwise formed. I have shown it as adapted for engaging with a lengthof hose. (Not shown.)

The extension E of the plug may be of other pyramidal forms than thetriangular form shown, care being taken to give a corresponding form andsize to the recess in the coupling which matches thereon.

The perforations c in the disk 0 may be reduced in number or omittedentirely, the perforations b in the bushing supplying liquid into theinner chamber, or, on the other hand, I can omit the perforations Z) andsupply all the liquid through the perforations c.

Other materials than brass may be used for the bushing.
